Hello all, I'm a newbie to the forum. I recently purchased a A4 and now I am finally getting to slowly modifying it.

Today I installed a new Pioneer headunit (p 660) and a 12' rockford p2 sub and amp. I guess all the electric wiring got a little screwed up in process. Now, my date display is wrong, I can no longer see the MPG information on the dash screen, and top part of that with the cd information is entirely missing (where it used to say "CD track 1, etc"). Whats the best way to remedy all of this? Thanks for your help.

By the way: the car is a 2000 1.8 t.

 

well the top part wont work with aftermarket HUs

as for the rest of it you might have shut it off accidentaly did you try turning back on using the mode button

 

Yeah the button on the winshield washer stalk.
